SPECIFICATION forming part of Letters Patent No. 727,375, dated May 5, 1903.

Application filed March 4, 1902. Serial No. 96,631.. (No model.)

To aZZ whom, it may concern:

Be it known that I, LEBBEUS JONES, a citizen of the United States, residing at New Cu inberland, in the county of Hancock and State of West Virginia, have invented a new and useful Improvement in Bailers, of which improvement the following is a specification.

This invention relates to certain new and useful improvements in sand-pumps for oiltion and arrangement of parts to be herein-- after more fully described, and specifically pointed out in the claim.

In describing the invention in detail refer-- once is had to the accompanying drawings, forminga part of this specification,and wherein like numerals of reference indicate like parts throughout the several views,in which- Figure 1 is a side elevation of my improved sand-pump. Fig. 2 is a longitudinal section of the same. locking mechanism in a locked position. Fig. 4 is a vertical section taken through the valve of my improved sand-pump. Fig. 5 is a top plan view of the collar carried by the stem of the valve.

In the drawings the reference-numeral 1 indicates the body portion of the pump, carrying on its upper end the bridge 2 and carrying on its lower end the interiorscrew-threads 3. Carried by these screw-threads is a collar 4, which in turn carries the screw-threads 5,

said screw-threads carrying the base 6 of the casing, the base having the apertures 7, arranged opposite each other. Located centrally within this casing 1 is a stem 8, which passes through the bridge 2 and through the collar 9, carried by the bridge 2. Upon said stem is secured a collar 10 by means of the set-screw 11, said collar carrying the spring member 12, which is secured by means of the Fig. 3 is an elevation of the screws 14, said spring member carrying on its lower end the projection 15. Secured to the side of the collar 10 by any suitable means is the locking-lever 16-, carrying a handle 17, said locking-lever having a cut-away portion 18 for the reception of the spring member 12. Secured to the top of the stem by means of the screw-threads 19 is attached the eye 20, to which is secured the rope. To the lower end of the stem is secured the valve by means of the screw-threads 21 and nut 22. This valve 23 has a number of apertures 24, passing up vertically through the valve. upon the top ofthe valve is the gasket 25, the liniit of said gasket being arranged by the position of the washer 26 and the nut 27, secured upon the stem, as indicated at 28.

The operation of my improved device is as follows: When it is desired to lift water from Seated the well, the pump is lowered into the same until the base of the pump rests upon the bottom of the well, when the valve-stem and valve will continue down through the casing until the valve has seated itself upon the base of the casing. When the pump becomes filled with water by means of the apertures in the side of the casing, the pump is then drawn from the well, and as the operation takes place the Valve proper will seat itself upon the collar, thereby holding the water in the casing until the same is drawn from the well. Upon reaching the surface of the ground the pump is rested upon the ground, and as the rope slackens the valve-stem will resume its natural position, as shown in Fig. 2 of the drawings, thereby allowing the water to pass out of the apertures located in the sides of the tubing. pump in such a position, so it will not hold any. wateigthis being the case when the pump is out of the well. In this event by turning the 1ocking-lever17 the spring member12 may be raised or lowered, as may be desired. By lowering the lever 17 the spring member will be permitted to move inwardly, thus locking the stem of the valve securely down on the collar 9 of the casing by means of the projection 15 of the spring member 12 becoming engaged in the projection formed by the head of the collar 9.

It will be noted that various changes may It may be desirable to lock the be made in the details of construction Without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a sand-bailer, the combination with the casing having openings in the base thereof, a bridge secured to the upper end of the said casing, a collar secured to the said bridge, said collar being formed with an annular flange, a stem operating through the said bridge and collar, a valve on the lower end of the said stem, a collar secured to the upper end of the said stem, a spring-catch se- LEBBEUS JONES.
